The operation of themachine is in general as follows:

Starting with the left-hand unit, the operator closes the female moldson the mold carrier and moves the batter supply mechanism intoregistration above the closed molds. He then operates a handle by whicha multiplicity of nozzles are opened to discharge a predeterminedquantity of the batter into each mold cavity. The mold carrying frame isthen moved rearwardly on its slidesinto a position of registration withthe burners below and the male cores above. By operating another leverat the forward end of the unit, the core carrier is caused to descendinto the molds forming the batter up around the cores and closing thecavity provided between the side walls of the female molds and theoutside walls of thecores. In giving this movement, the operator worksthe cores up and down slightly, allowing expansion to take place and thesteam gases to escape, after which the cores are secured in bakingposition by a toggle effect of certain levers in the actuatingmechanism.

The operator then proceeds in the same fashion with each one of theeight, or more units of themachine, the length of time taken to performthese operations on the remaining units of the machine being gauged toallow the complete baking of the batter introduced in the first unit.The operator then returns to the first unit, operates the core carrierto raise the cores out of the mold so that the subframe with thefinished baked cones may be withdrawn from the oven and located over adischarge trough. In this preferred embodiment of the invention thefemale molds are arranged in separable halves so that by the use of ahand extractor having a series of properly spaced projections, theoperator may split or separate the molds and push off the cones at thesame time. As the cones are pushed off, they fall from the open moldhalves and are directed by the discharge chute usually through the floorof the building to another department where they are stacked andpackedfor shipment.

Referring now more particularly to the drawing there is indicated at 20,(Fig. 3) a flooring through which passes a discharge chute 21 having anenlarged mouth 22.

The main frame is built up from the fioor- 7 ing by spaced uprights 23,longitudinal angle irons 24 at the rear of the machine, and longitudinalirons 25 at the front of the machine.

'core.

uprights 23. Upper slide bearing pieces are fixed to the rails 26 andlower slide hearing pieces 31 are fixed to the members 29, the structureforming vertical slide bearings for a core head 32 which has oppositelydisposed vertical slides 33 arranged in the bearings.

Lengthwise of the machine, but traversing the individual units thereof,is a pair of rails 34. These rails are supported by uprights 35 from theflooring 20, the uprights tying to the rails 26 as indicated at 36. Therails 34 extend some distance beyond the extreme left hand unit as shownin Fig. l. of the drawings so that a batter supply mechanism 40 arrangedfor sliding movement on the rails may be movedto a position of restbeyond the units, enabling the operator to manipulate the molds of thefirst or left hand unit without the interference of the batter tray.

The fuel supply is by a gas main 41 coming through the flooring 20 andfrom which separate feed frames 42 run to the individual units betweenthe rails 26. The feed frames 42 supply thefuel for heating the moldunits from below. For heating the cores on the core head 32 a series ofpipes 43 is fixed above the core head and connected to the main 41 byflexible conductors 44. Individual valves are provided for the core gasfeed and the mold gas feed and these valves are controlled by handles orhand wheels 45 and 46 respectively, arranged at the front of the'machineand at each unit.

The mold carrier'27 of each unit is in the form of a rectangular frame50 in which are journalled wheels 51 adapted to roll on the trackconstituted by the spaced rails 26. The side pieces 52 of the frame 50form a slide for a plurality of split female molds 53, the'frame beingsufficiently long to permit the comple- 'mental mold sections to beseparated successively to allow the baked products to be extracted. Eachpair of female molds is formed with mold cavities 55 so that when closeda cup or cone shaped opening is formed to receive a charge of batter andthe male In this present embodiment of the in vention there are eightbaking units. Each baking unit comprises ten mold pairs and each moldpair is formed with seven cavities. The baking time allowed for eachunit is from two and a half to three minutes. This allows the operatorsuitable time to do the unloading and refilling operations on theremaining seven units, returning to the first unit at the end of thebaking period to unload and refill. The capacity of the machine is,therefore, per unit of baking time five hundred and sixty cups orapproximately ten thousand per hour.

The core head 32 carries seventy male cores each mounted on the head bya bolt, the shank of which passes through a hole in the head slightlylarger than the shank. This allows the cores a slight lateral shaft inany direction to adjust the cores to the molds when the head is moveddownwardly into forming and baking position. v

The actuating devices for the core head and the mold carrying frame areshown best in Figs. 1 and 30f the drawings. On' lugs 61, spaced on andprojecting from the front cross piece of the mold carrying frame, twoarms 62 are pivoted. These arms with a cross connecting rung 63constitute a handle by which the said frame may be withdrawn from andreturned to the burners. The arms 62 extend I upwardly or inwardlybeyond the pivot points onlugs 61, and pivotally connect at 64 withlinks 65 which in turn-pivotally connect with lugs 66 secured to thefront wall of the most forward femalemold section 53.

When the handle 63 is moveddownwardly around its pivot on lugs' 61 theforward moldsection is moved forwardly separately from itscomplementalsection. Theother I molds are then broken by the operator with the useofa handle 7 0 shown by dotted lines in Figs. v4 and 5, the handle havinga cross bar 71 reinforced by diagonal struts 72. The cross bar has aplurality of depending fingers 7 3 of suitable shape and in numbercorrearated from the walls of the 'mold cavities I and they then droptothe chute 21. The completion of this operation leaves the molds as shownin the second unit of the machine in Fig. 1. of the drawings."The'operato'r thenmoves the handle upwardly, which, through links 65moves the mold sections back. closing the gap at'the rear of the moldcarrier and locking the sections together'by a toggle effect of linksand lever arms'62, as clearly shown in Fig. 3.

The core heads are moved upwardly "and downwardly by handles andconnected links and levers as follows. ,Ineach'unit the slides 33 towhich the core head is connected have attheir upper extremities aconnecting cross pivoted link couples the bar bar 80. A 80 with one end81 of a beam 82 fulcrumed at 83 on the main frame. Theother end- 84 ofthe beam is pivotally connected at 85 to the upper end of a link 86, thelower end of which has a pivoted connection at 87 with v an arm 88journ'alled in a fixed bracket 89. Thearm has a connection by means of along link 90 with a lever 91 j'ournalled in a fixed bracket 92 at thefront of the machine. The

upper end of lever 91 is formed as a handle 93..

Movement of the: handle upwardly into the position shown by the fulllines in Fig. 3 forces the core head down causing the cores to enter themold cavities and finally locks theparts .by a toggle efi'ect oflink86:.and v arm.88. A counterbalance weight 94 is suspended from the endOfllllQ beam 82 to assist the operator in lifting the. core head. .Sheetmetal cover plates 95 may bearranged over; the gas feed for the corehead, asshownin" Fig. 1 for the purpose of confining the heat.

In the modified form of core actuating means shown in Figs. 9and,10 ofthe drawings,- additional pressing and toggle. locking means areemployed for the purpose of applying pressure at a plurality ofpoints ontheocore head. An extra framelOO is built up on each rail 26, supportinga cross bar 101. Journal boxes 102on either side of the unit centervline, have pendant links 103 connected to link" 104 by pivot'pins 105.Thelinks 1 04connect to the crossbar, 80 in the same manner'as links 80are connected. Pivotally secured to the. joined ends of links 103 and104 by the pivot pin 105' is a linkol06 which'connects at 107 with aforked connection 108. Opposite V with extensions 110 of the uprights23, .and

below at 11 1 with the arm 88 by pivot pin 87.;

By this construction the arm 88 controls the toggle links 103 and 104 aswell as the toggle link 86. Movement of'the handle 93 applies pressureat three jpointson the' cross-bar of the core head and locks the. latterwith its 7 branches of the fork ,108connect above at 109 cores. in-vthemolds by actuatingthe three toggles. Generated steam 'and thebatterexpansion under the heatofthe molds-exerts a greatupwardpressure'on the core head. The

modified form of "locking'means serves-[to resist this pressurekandholds" the core headfirmly down against the molds, fresulting in a highdegree of cups.-,.

The batter supply mechanism '40 comprises bearings in straps 121. thebatter supply tray may be moved along when all have been supplied thetray may be returned to a positionat the left ofthe machine out ofregistration with'any of them.

The tray l20 has a sheet metal bottom 124 andupstanding walls .125(Figs. 6, 7 and 8). Spaced barsv 126 extend lengthwise of the tray andpartitions 127. are provided to: fill the spaces between the bars. These"partitions have their tops infthefform of an inverted V,

as clearly shownin Fig. 8,'permitting the bat-' ter to flow and fill thespaces between the partitions. Discharge openings 128 are formed thebars and'tray' bottom, the openings belng normally closed by a framecomprising a-I'nultiplicity'of closure slidesql29, one for uniformity 1in the baked each opening, spaced apart and connected in rows. to slidebars 130, which in turn are atg tached toa cross bar 131. The portclosure frame is operated by a handle132 fulcrumed 1 "105 a rolling traysuspended bystraps121y. from rails and having rolling engagement,thereonby meansof wheels122having their I By this construction 5110 athe rails to register with successive units and at 133 on a lug 134:projecting from a cross bar 135 which is a part of a subframe connectedto the main frame of the tray.

The handle 132 at its lower end has a pin and slot connection with thecross bar 131 of the part closure frame. A spring 136 pulls the handlein a direction to close the discharge opening.

After the mold carrier has been withdrawn from the ovens, the contentsof the molds discharged, and the molds re-closed as herein previouslydescribed, the batter supply tray is moved along the rails into exactregistration with the mold carrier. The operator then moves the handle132 opening each of the ports 128 simultaneously, letting drop aquantity of batter in each of the mold cavities. As the operatorreleases the handle 132 the spring 136 returns the slide frame to close'the ports. An equal quantity ofbatter is dropped into each cavity. Anadjustable stop 140 is provided for arresting the movement of the handle132. The operator re leases the handles as soon as this stop is reachedso that by varying the position of the stop the opening time of theports may be varied. This provides for gauging the amount of batterdelivered to the molds.

To more accurately determine the amount of batter delivered, the form ofdelivery tray shown in'Figs. 11 and 12 may be used. In

this formthe tray bot-tom is above the valves as indicated at 150androtary plug valves 151 are arranged below. The valve casings 151 haveupperandlower ports 152 and 153 respectively. The valve plug has a port154: adapted to be moved into and out of registration' with the inletport 152. The plug has an outlet port 155 adapted to be moved into andout of registration wit-h the delivery port 153. Lengthwise of the valveplug, which is hollow,'there are partitions 156 forming chambers, sothat when the tray is filled with batter and the valve inlet portsregistered with openings 157 in the tray bottom, a quantity of batterwill be received in each chamber. Each valve plug has at one end a lever158 connected to a bar 159. The bar is operated by a handle 160 betweenadjustable limiting stops one of which is shown at 161. If desired aspring may be used for elfecting the return movement. 7

The split female molds are shown as having top'plates 170 providing lips171 with recesses 172 for the batter overflow.

The advantages of these plates are fully set forth in my copendingapplication Ser. No. 77,910, filed December 28th, 1925, for improvementsin automatic machines for making cup pastry. These plates have onespecial advantage in the present machine not apparent in the automaticmachine. The lips 171 form the opening which receives the fingers 73 ofthe extracting rake 70.
